The bass player, 25, apparently proposed to Patterson, a 21 year old model, last month on April 11.

Rolling Stone reports that the pair have only been dating a few months. Followill confirmed the news earlier today via his Twitter account (@youngfollowill), joking: "It's true! I'm engaged! CANNOT wait to finally lose my virginity."

Following his online revelation, The Strokes' Nikolai Fraiture responded: "Congrats man! You're gonna love it!"

Bang Showbiz reported that Jared popped the question with a four-carat cushion-cut diamond, set on a diamond band, which he designed himself.

His representative told JustJared.com: Yes, it’s true! Jared proposed to Martha on April 11 at his home in Nashville and we’re all excited for the newly engaged couple.”

The report said the couple plan to divide their time between their homes in Nashville and Los Angeles.

The wedding date has not yet been revealed.

Earlier this year, Kings Of Leon hinted that they could start work on a new studio album at some point in 2012, reported NME.

Speaking to MTV, drummer Nathan said the band had repaired their relationship after a tumultuous 2011 and would "probably start kicking around" some new ideas in the studio soon.

The Tennessee stadium rockers were forced to cancel their entire US tour last year after frontman Caleb stormed offstage in Dallas in July and was deemed too ill and exhausted to tour, with his bandmates later plagued by rumours that they wanted to kick him out of the band and were forcing him to go to rehab.

However, Nathan claimed that the band were now on good terms and also revealed that they had purchased a studio in Nashville and were hoping to start working on new material there soon, adding: "We're going to spend the next few months getting that up and running; kind of make it our little clubhouse to get there and just kind of goof off whenever we want to."
